RAMP submission explanation

[lucyleeow]

The notebook just points to: https://paris-saclay-cds.github.io/ramp-docs/ramp-workflow/stable/using_kits.html but does not explain the basic details:

• requires estimator.py file
• define a get_estimator fun with the file which needs to return a sklearn pipeline or estimator

Yes explaining this after the first submission would be very helpful! :)
